I question whether this is a viable long term business. This quote from a Wall Street Journal interview describes their strategy:
********************************************************
Paypal's developer, Nokia-funded Silicon Valley startup Confinity Inc., is aiming to be at the heart of both e-commerce and m-commerce.
Confinity says Paypal users may at first be hesitant to use the system for more than small payments, but its use could grow rapidly if it proves
successful initially. It says that a year ago, online share traders cautiously traded small parts of their portfolio over the Web, but today, many
investors have their entire portfolio in online accounts.

Confinity's founders are betting they can make money with Paypal by drawing interest over money payments that haven't yet been claimed.
While merchants usually cash in on payments and checks as soon as possible, many individual consumers aren't as quick. "We are counting on
a certain stickiness of the money," says Peter Thiel, Confinity's chief executive officer, who adds, "People don't pick up money until they need
it."

We'll see. It's certainly an interesting experiment. Just remember: they will be holding your money till you claim it. If they go out of business, your money in transit is lost. All the more reason for people to claim their credits immediately.
